Terminology
Q: Can you review some basic terms used on your site?
A: Sure!
Screen Printing - the technique of pushing ink through open areas of a screen so that an image or pattern is printed onto a substrate.
Silk Screening - often used synonymously with screen printing, silk screening or silk screen printing is a much older term. Previously, silk was mainly used as a raw material in the manufacturing of the mesh. Today, mesh is typically made of more durable, synthetic fibers such as polyester. Even so, the phrase "silk screening" is still sometimes used, but mainly by an older generation. The phrase "screen printing" is a more accurate description of today's process and is gaining in popularity.
Emulsion - a UV light-sensitive substance that hardens when exposed to UV light (ie. our UV LED, sunlight, DAYLIGHT fluorescent bulbs, tubes, etc. SmallDogPrints' emulsion is orange. For ease of use, our emulsion has already been applied to a stretched mesh fabric. Since our emulsion is UV light sensitive, it ships in a UV light protective baggie.
WARNING: All handling of Emulsion on Mesh Film before/during exposure & while developing should be done with safe lights on in a darkened room. Only when the Emulsion on Mesh Film has been made into a screen stencil is it safe to turn on regular UV lighting. Film could cause an allergic skin reaction and/or serious eye irritation. Wear protective gloves and eye/face protection when handling.
EXPOSURE - the process of revealing our orange Emulsion on Mesh Film to the correct UV light source so that the light sensitive orange emulsion hardens. NOTE...the black ink printed on your transparency protects these areas of emulsion from hardening and so these areas will rinse away ... thus creating your custom screen stencil.
To expose film perfectly every time, purchase our inexpensive UV LED light kit and expose from 12" away for one minute. If using an alternative light source, it is important to use UV bulbs that closely mimic the natural sun. ie. DAYLIGHT fluorescent bulbs with high kelvin ie... 5000k - 6500k, a "grow light" or "grow light box" used indoors for growing plants, etc. Use our TEST STRIPS included in each purchase to decide the best distance/time, etc.
A single bulb like the one below can be used 12" away from your work surface and exposes film in about 15 min.https://www.1000bulbs.com/product/111160/TC-ES05023WCWTF.html
A "grow light box" like the one below can be used from 4" away and exposes film in about 3-4 min.https://www.1000bulbs.com/product/91487/GROW-FLP24.html
Safe Lights - Lights & bulbs that do not emit high amounts of UV rays and will therefore not expose/harm Emulsion on Mesh Film. We include a yellow safe light bulb in each Complete Kit and Light Kit purchase so that you are able to see in your dark room before/during exposure & while developing screens.
Mesh - a thin, light-weight material made of a network of polyester threads woven together.
TPI (Threads Per Inch) - a.k.a. “thread count” or “mesh count” this refers to the number of threads used per inch of fabric. For example, a 110 TPI would have 110 threads crossing per square inch. 110 is typically used in screen printing as it is the least expensive fabric and is widely available.
IMPORTANT: SmallDogPrints uses a proprietary mesh which has a much higher TPI. Our higher thread count offers artists the perfect balance of high detailed designs without limiting the mediums that can be used with screens (ie. Mica powders, metallic inks, etc.)
In addition, a higher thread count provides a tighter weave which is more durable and produces thin, pliable screens that conform nicely to a variety of substrates including curved surfaces! See video tutorial for Print Curved Surfaces here.
Lastly, the higher thread count contributes to the fast drying nature of our screens!
Medium - artists' term for the material used for printing (i.e. underglaze, acrylic ink, enamel, fabric ink, etc.) NOTE... when printing with screens, mediums should be thick and have the viscosity of mayonnaise. For a list of various mediums recommended for a variety of substrates, go to the end of this FAQ and see the section "Mediums & Substrates."
Substrate - artists’ term for the underlying material on which various mediums are applied. SmallDogPrints’ screen stencils are the most versatile on the market! Other screens are best suited for fabric but not for hard surfaces like bisqueware or vice versa. With SmallDogPrints' screen stencils, you have the ultimate in flexibility! Because our screens are not only reusable but also durable, they can be used to print on a variety of substrates including: ceramics, polymer clay, fabric, paper, glass, metal, wood, foam, felt and more!
For a list of recommended mediums for various substrates, go to the end of this FAQ and see the section "Mediums & Substrates."
Screen Stencil - a product made with our Emulsion on Mesh Film. Screen stencils can be used to print on substrates by the application of ink or paint through the mesh openings.
Viscosity - term used to describe the thickness or consistency of a medium (ie. ink, paint, underglaze, etc.). IMPORTANT: Generally speaking, when printing with screen stencils, thicker, more viscose mediums produce prints with the cleanest, crispest lines & edges. The viscosity of the medium used should resemble the consistency of mayonnaise or even paste.
There are many methods & products available which can help to thicken various mediums. For example, simply leaving a small portion of acrylic ink out & uncovered can help some of the moisture to simply evaporate. Other artists use small amounts of corn starch and blend very well as a simple thickening agent.
For thickening agents available for purchase, check out Liquitex's line of thickening agents including Liquitex Liquithick Thickening Gel Professional Effects Medium for acrylics (available here on Amazon). To thicken underglaze for ceramics, my favorite is this Mayco Silkscreen Medium (available here at Blick Art Supplies). When screen printing on glass, this Colorline Silk Screen Paste is pre thickened and produces great results right out of the tub! You can find it here at bullseyeglass.com. Here's a Youtube tutorial for it.
PROCESS
Q: What types of designs are best to print on the PRINT SIDE of transparencies?
A: Using artwork with high resolution is very important.
When getting free clip art online it is best to use .svg files (ie: .pdf / .ai / .eps / .svg). These are considered vector artwork and will allow the user to resize or rescale the image without hurting the resolution of the design.
Also, printing images on transparencies with the darkest resolution using 100% black ink (hex code: #000000) always makes screen stencils with the cleanest, crispest edges and best details. Either hand draw artwork on the textured side of transparencies with a black oil based paint marker OR use your ink jet or laser printer set to the highest, darkest resolution possible. Remember, the black print on transparencies is what blocks your UV light source from baking the emulsion on film. Therefore, the black print needs to be dark enough to block any UV light from going through these areas. To experiment with this, try going over some areas of a printed transparency with a black, oil based paint marker making some sections EXTREMELY dark while leaving other areas just normal print. After exposure when you are "washing out" the screen, you will notice that the areas that had the darkest ink printed on the transparency will wash out the quickest and have the cleanest edges. Again, printing with the DARKEST INK possible on your transparency is important to adequately block the UV exposure light from "baking" the emulsion on film.
Q: Can I use my professional light table, DIY light table or other artificial light kit that I already own to expose film/designs?
A: Our craft centers, ceramic shops and artists have reported that MANY artificial UV LED, tube lights & bulb arrangements have worked for them with amazing results! The problem is that there are simply too many variables for us to list all of the possible combinations!
In general, if deviating from our recommended UV LED blacklight included in kits, artists will need to consider the types of bulbs they are using, their exposure times and the distance the film/artwork sits from their UV light source when they are exposing film. Multiple tests should be expected.
In general, broad spectrum DAYLIGHT fluorescent or blacklight UV bulbs (5000K - 6500K) are the most effective for exposing our Emulsion on Mesh Film as these most closely resemble UV rays from sun exposure. It is also important to have fluorescent or black light fluorescent tubes or bulbs (i.e. CFL bulbs) with a UV rating between 380-395 nanometers AND the highest wattage possible.
IMPORTANT TIP: If it is not possible to have a dedicated "dark room" for exposing film (ie. no windows or natural light) many users simply expose film at night.
WARNING: Care should be taken to NEVER use any electrical device in or around water.
WARNING: All handling of Emulsion on Mesh Film before exposure should be done with safe lights on in a darkened room. Only when the Emulsion on Mesh Film has been made into a screen stencil is it safe to turn on regular UV lighting. Film could cause an allergic skin reaction and/or serious eye irritation. Wear protective gloves and eye/face protection when handling.
Q: Why are there some areas where too much emulsion washed out of my screens and therefore I lost some wanted details (ie insides of letters, etc.)
A: If too much emulsion and details wash away, the film has been underexposed (i.e. undercooked and not baked long enough). Artists should consider INCREASING the amount of exposure time and/or decreasing the distance their bulb(s) sit(s) from the film/artwork.

Wear protective gloves and eye/face protection when handling.
Q: Why are there areas where some of the emulsion did not rinse out of my screen even though I softly and thoroughly sponged/sprayed it during development?
A: When developing film into a screen stencil, emulsion should quickly rinse off the design areas with a gentle sponge and/or sink sprayer. Artists should not feel that they need to “scrub” or “fight” to develop screens at all. If not enough emulsion washes away & it is difficult to see through areas of the design that should be open, the film has been overexposed (i.e. overcooked and baked too long). Artists should consider decreasing the amount of exposure time and/or increasing the distance their bulb(s) sits from the artwork/film.

Wear protective gloves and eye/face protection when handling.
Q: Can I cut film to smaller sizes before exposing?
A: Yes but make sure to handle film in a darkened room with only safe lights on to see. An alternative idea is to create an 8.5” x 11” sheet of artwork with various small images on it but separated by fine lines. After you have created your sheet of screen stencils and it is dry, you can simply cut them apart using the fine lines as guides. Make sure to keep at least a half inch border around each design so that you can hold or tape your finished screen stencil to your substrate and to leave room for ink to pool at the edges of your screen stencil.
Q: Can I soak, develop or clean more than one at a time?
A: Sure! SmallDogPrints does not have one side with a dedicated “sticky back” so multiple sheets of film can soak together either in your black developing box (making sure not to crease your film), or in a sink as long as enough water allows them to float on top of each other and the stack is covered by your black board. While sponging to develop a screen stencil, just make sure the others stay covered by the black board until it’s their turn to be developed! For the same reasons, after printing, multiple screens can be placed together in water to soak, awaiting cleaning.
Q: How long should film soak after exposure? How long should I softly sponge/spray film to develop my screen stencil?
After exposure, film should soak in lukewarm water for about 10 min in our black developing box or in a sink with floating film covered by a black board. Softly sponge/spray the film with cool water for about 30-60 seconds to develop your screen stencil. Continuing beyond this point may inadvertently wash away wanted areas or details in your design ie. centers of letters, etc. It is helpful to have a yellow or red safe light bulb to see if all the design areas have indeed washed out before finishing with developing.
WARNING: Care should be taken to NEVER use any electrical device in or around water.
WARNING: All handling of Emulsion on Mesh Film before exposure should be done with safe lights on in a darkened room. Only when the Emulsion on Mesh Film has been made into a screen stencil is it safe to turn on regular UV lighting. Film could cause an allergic skin reaction and/or serious eye irritation. Wear protective gloves and eye/face protection when handling.
Q: Are there special storage requirements for film? Will film expire?
A: Film should always be stored flat (or loosely rolled for Oversized Film) in its original, UV light protective packaging. Film should simply be stored at room temperature (do not expose to extreme heat & do not refrigerate). Film performs best when used within 18 months of purchase.
Q: Can I print designs with more than one color?
A: To achieve this effect will require some extra steps. One way is to make a screen stencil and temporarily block out areas of the design that you don’t want to print with some LOW TACK tape. Using corner registers on your item, print with the first color, then completely clean and dry your screen stencil. Next, use LOW TACK tape to block out the other areas you don’t want to print and print again making sure to line up your image correctly using your corner registers as a guide. Another idea is to create multiple screens where each screen is used for each color of the design.
Q: Can I flip my screen stencil over and print on either side?
A: Yes. Screen stencils are reversible. SmallDogPrints does not have one side with a dedicated “sticky back” so our screen stencils are extremely versatile. Ie. An image of say, a squirrel facing left, can quickly be flipped and used so that the squirrel could also face right. Even so, flipping the screen to print on the non squeegee should be done only on occasion and can possibly reduce the life of the screen.
Q: How do I secure a screen stencil so that it does not shift when printing?
A: Depending on the size of the screen stencil and how many prints you need, there are various ways to secure them. Generally speaking, for tiny screens where only one print is being made, the edges of the screen can simply be held in place with fingers while ink is being applied by a brush, Qtip, old gift card, etc. For larger screens where only one print is being made, it is advised to secure the screen with painter’s tape around its edges so that the screen lays flat and is smooth. Lastly, for repeat printing with larger screens, secure one of our black, plastic, reusable frames to the front of your custom screen stencil with either double sided sticky tape OR spray the black, plastic, reusable frame with some repositionable spray adhesive on one side of the frame so it will stick to the front of your custom screen stencil. Then, tape the frame to a hard, FLAT surface with no bumps in it (i.e. a clean craft table) with tape on only one side creating a “hinge” effect (click here). This is great for repeat printing of ceramic tile, greeting cards and other items. Please refer to our video tutorials for Printing with Screens (click here).
Q: What type of ink can I use to print with my screen stencils?
A: Thick ink always works best with screen stencils as it is the easiest to control and provides great coverage. Ink or paint which has the viscosity of mayonnaise works best. Water based acrylics, fabric ink and others can easily be thickened by leaving a small portion out uncovered. Also, adding tiny amounts of corn starch and blending well can help to thicken ink and paint for more immediate use. Again, be sure to blend well.
For ceramics, try adding some Silkscreen Medium to underglaze to thicken it up (Mayco has a good Silkscreen Medium here). About 1/2 tsp. of Silkscreen Medium for every 2 oz. of underglaze works well. Again, make sure to blend well so that there are no lumps! This may take awhile but smooth ink, paint, underglaze, etc. will be well worth the extra effort! I have a video tutorial here).
Q: How many times will I be able to print with a screen stencil?
A: This depends on how you care for and store your screen stencils. After printing, care should be taken to gently clean screen stencils in water and to not allow ink, glaze, etc. to dry in screens. If you are printing with multiple screens and find you don't have time to clean them right away after printing, try keeping a bowl of water out on your craft table. Make sure it's large enough to place your ink filled screens in it so they lay flat and are completely submerged in water. They can hang out in the water until you have time to clean them! The water should keep the ink from drying in the tiny mesh openings in your screens and ruining them. Keep in mind, water softens the emulsion in your screen stencils so don't forget about them in there!! Also remember to GENTLY clean them with a SOFT sponge when you finally do have a minute to clean them. No hard scrubbing allowed! :)
Also, screens need to dry FLAT with the dark orange side facing up. Reposition screens often so they do not dry to your work surface.
TIP . . . a long time ago I decided I was using way too many paper towels in my studio so I bought a large, canvas painter's tarp at Lowe's here. I washed, dried and ironed the tarp so it would lay FLAT on my craft table in my studio (like a table cloth). I LOVE this set up so much! No longer do I need so many paper towels and the canvas painter's tarp is a wonderful surface on which to dry screen stencils!!
SmallDogPrints uses our own screens to print our white stay flat envelopes as well as our black plastic baggies. Our screen stencils have been used 100’s of times and are still going strong!
Q: What’s a good way to store all of my screen stencils?
A: A simple 3-ring binder with clear plastic sleeves seems to be the preferred way for our artists & studios to keep their screen stencils organized.

MEDIUMS & SUBSTRATES
Q: Can you recommend a few mediums that work well with SmallDogPrints screens when printing on different substrates? How do you thicken? How do you seal?
A: Sure! Below are just a few of the various types of inks, paints, glazes, etc. that work well with SmallDogPrints' screen stencils along with ways to thicken & seal them!
CLAY, BISQUE, CERAMICS: Medium: Amaco Velvet Underglaze or Mayco Stroke and Coat Wonderglaze. To Thicken: Mayco Silkscreen Medium (2 oz. Wonderglaze + 1/2 tsp Medium) Be sure to blend well! Tutorial here. To Seal: Brush or dip in glaze and fire in kiln.
FABRIC, PAPER, WOOD, METAL, PLASTIC: Medium: Blick Waterbased Acrylic Fabric Screen Printing Ink - good multipurpose ink that is very similar to the Speedball brand but a little more reasonably priced. To Thicken: Leave a small amount out overnight to help water evaporate, or add small amounts of cornstarch (blend well til no lumps!), or Liquitex Liquithick Thickening Gel (easiest). Cure: Let your printed item dry at room temperature and/or dry with a hair dryer. To Seal for fabric only: flash drier or cover design with a paper towel & iron 2 min. To seal wood/metal: Rust-Oleum Painter's Touch 2x Ultra cover matte clear spray for wood, metal, plastic & more (spray) Seal prints on canvas: Liquitex Satin Varnish Spray. Most paper products need to simply dry and do not need to be sealed.
POLYMER CLAY: Medium: Liquitex Heavy Body Acrylic. More expensive than Blick (above) BUT more versatile. Print polymer clay PLUS fabric, paper, wood, stretched canvas, ceramics, bisque, glass, etc. To thicken: Already very thick. To thicken further try Liquitex Liquithick Thickening Gel.Seal: Golden Acrylic Polymer Varnish (brush on) or Varathane Diamond Wood Finish Crystal Clear Gloss for polymer clay or wood (brush on). Note...Kato Clay is the best type of polymer clay if you will be screen printing on it. Kato Clay does not have excessive plasticizers in it which can cause acrylic ink to remain sticky & hard to dry. If your ink still does not dry within 10 min of printing, try leaching the clay before screen printing. In general, it is recommended to bake all screen printed polymer clay as soon as possible.
GLASS: Medium: Chalkology Ink . Chalkology Ink is recommended for glass but Chalkology Paste is not. To Thicken: No need to thicken. Seal: Bake the Chalkology Ink printed glass in 350° oven for 30 min. Heat up and cool your printed item slowly.
GLASS & CERAMICS: Medium: Color Line Silk Screen Paste (enamel). To Thicken: No need to thicken. Seal: Recommended firing temperatures are 700℃ to 820℃ (1300℉ to 1510℉). Compatible with art and float glass COE 85-96 and ceramics.
